Micro-Kubik

ukubik.jpg

This is a work in progress project. The idea is to build a quadruped, three degrees of freedom per leg, robot – but make it as small as possible.

The idea is to only have the minimum of electronics inside – an arduino for the servo controller, and a bluetooth module for communication – then do all the calculations remotely, on a computer. Later I might use some generated precomputed tables for the inverse kinematics, though.

Bill of Materials

Name Quantity Unit price Total price

Total $75

(You can probably drop the sensor.)
